What size baby sleeping bag do I need?


The Merino Kids® Go Go Bags® (baby sleeping bags) come in two convenient sizes:

  • Baby - The 0-2yr Go Go Bag can be used from newborn (minimum weight 3.2kgs/7lbs) by fastening the domes (poppers) under your baby's arms for about the first 6 months. It is designed to be worn until your baby's toes are touching the end of the bag. There is plenty of width and room for baby to grow into the baby sleep bag.
  • Toddler - The 2-4yr Go Go Bag can be used from 12 months if your baby is on the tall side, again just fasten the domes (poppers) under your baby's arms. They should grow out of needing to be in a sleeping bag before they physically out grow this size. See link here for how to transition baby from cot to bed and how the toddler sleep bag can help with this transition.
Size Guide Chest Width (at knee position) Length
0-2yrs (Baby) 28cm 53cm 86cm
2-4yrs (Toddler) 32cm 60cm 104cm

Please note: Our sizing is based on average sized babies so please take into account what growth percentile your baby is in and buy the right size for now, rather than worrying about how long it will last. We are all about safe sleep and it's important that your Go Go Bag fits and there is no danger of baby slipping into a bag that is too big.
